Gasp! Are cross-country cycle routes being made in Ireland?

I have noticed cycling signs like this in Wexford and Westport of late.

Does this mean there is some type of network of cycle routes emerging?!? Or are they just local initiatives doomed to neglect and becoming moribund as soon as the first sign if knocked over?

During my recent holiday in Wales I was green in envy (& admiration) of the cycling facilities they have there. They are part of the Sustrans system. Entire cross-country cycle routes through gorgeous scenery with clearly signed and waymarked routes.

PS - I just discovered this PDF of a supposed "National Cycle Network, Ireland" (PDF). That explains the signs I have seen - but I am still skeptical. So many initiatives like this fail thru lack of proper maintenance & care that I wait to be convinced.
